Hi, and a belated happy new year !

I expect i am being stupid here. I am using pb2019 - and i have noticed when i go to edit data in a datawindow the existing data is not highlighted, in older versions the existing data was selected and if I typed at all it would be overwritten. this is no longer happening and i have had some users complain. 

for example i am editing a sales invoice - the line says

1 Item @ 0.00

each is in a different field if go to 0.00 to change the price i would have to delete what is there the 0.00 before i could put in 6.50 

I am sure this is really simple but i cant find it 

Any help greatly appreciated.

Andrew
